Title: Section air quantity detector
Inventor: KITA TOORU
IPC: G01F1/32
Filed: 1979-10-22
Abstract: PURPOSE: To stabilize the Karman vortex and reduce the pressure loss of sucked air, by providing the Karman vortex flow meter in the detection duct having an approximately angular section fixed to the straight tube part of the air suction tube.  
     CONSTITUTION: Detection duct 13 having an approximately angular section is fixed to straight tube duct 10 constituting a part of the air suction tube by arm 11 so that center lines of both ducts may agree with each other, and vortex generating material 14 for Karman vortex flow meter and heat coil 15 of a vortex detector are provided in duct 13. Therefore, since the distance between vortex generating material 14 and the wall face of duct 13 can be 3W4 times as long as the width of the vortex generating material, generation of Karman vortex can be stabilized and increment of pressure loss for the maximum air suction quantity of the engine can be suppressed. Further, since it is unnecessary to give the angular section to the air suction tube itself, it is unnecessary to increase the length of the detecting part for the purpose of preventing flow disturbance, and reduction of the number of degrees of freedom for mounting of the detector is prevented.

IPC: H03H3/08
Filed: 1981-08-28
Abstract: PURPOSE:To extend a cross length of a side lobe without changing weighting of electrodes, by splitting the weighted electrodes into at least parts taking a main lobe as major component and parts taking side lobes at both sides as major component. CONSTITUTION:Weighted electrodes are split into a main lobe part 5 and side lobe parts 6 and 7 at both sides of the part 5.

Taking a voltage applied between electrode fingers of the electrode 5 including the main lobe part as V, a voltage, V/2 is applied to the electrode fingers of the electrodes 6 and 7 including the side lobes. Since the intensity of excitation of surface acoustic waves is proportional to the product between the cross length and the applied voltage, the intensity of excitation is unchanged even if the cross length of the side lobes is extended twice, that is, the weighting given to the electrodes can not be changed.

Title: Sense amplifier
Inventor: KAWAUCHI KOICHI
IPC: G11C16/06
Filed: 1988-06-01
Abstract: PURPOSE:To simplify the title amplifier and to reduce energy consumption by inputting a clock to the gates of a pull-up transistor (TR) and a source TR, adding a pull-down TR to a detecting terminal, and connecting a clocked inverter to a detecting voltage terminal. CONSTITUTION:When a precharging signal 11 generated from a timing generating circuit 10 is set at an L, since a source TR 4 is turned off and a precharging TR 1 is turned on, the detecting voltage terminal is precharged at VDD. At such a time, a low constant voltage signal 8 is generated by a constant voltage circuit 7, and a drain 15 of a memory cell 3 is set so that only the low voltage may be impressed from a constant voltage signal 8. Next, when the signal 1 is set at an H, since the TR 1 is turned off and the TR 4 is turned on, a charge is pulled out or not pulled out by turning on/off the memory cell 3. When the cell 3 is turned on, the detecting voltage gradually falls, and an output 9 is obtained by latching the voltage. When the cell 3 is turned off, since the detecting voltage VDD does not change, the voltage is dropped by sending a pull-down signal 13 to a TR 5.

Title: Ae monitor device
Inventor: SHINOMIYA YASUO
IPC: G01N29/14
Filed: 1979-10-22
Abstract: PURPOSE: To measure effectively characteristic parameters of a desired AE wave, by deciding the sensor which received the AE wave first and by extracting only the receiving signal.  
     CONSTITUTION: When sensor 1a out of plural AE sensors has received the AE wave first, FF7a is set first by the output of discriminator 4a because the signal detection dependent upon discriminator 4a is earliest. Control circuit 8 inputs the set output of FF7a to reset other FFs and resets FFs 7bW7n and sets only FF7a independently of outputs of discriminators 4bW4n. Consequently, only switch SW 5a is conductive, and the receiving signal from sensor 1a which has received the AE wave first is supplied to parameter measuring circuit 6 in an alternative way, and the characteristic parameter is measured. As a result, the characteristic parameter of the AE wave can be measured effectively.

IPC: H01L21/027
Filed: 1980-09-30
Abstract: PURPOSE:To eliminate the need for a ferrite shield, by controlling sensitivity of a deflection amplifier, which sends out deflection current, to compensate frequency characteristics of an electromagnetic deflector, for an instrument in which a beam is deflected and scanned with an electromagnetic deflector. CONSTITUTION:An electromagnetic deflector 7 is arranged close to an objective lens 8 in an instrument. Deflection current is supplied from a deflection amplifier 13. While scanning, clock period T determined by resist sensitivity is informed from a CPU11 to a memory 15 through a register 12. T and sensitivity ratio for a frequency of T at lower frequencies are stored in the memory 15. They are read out and informed to a multiplier DAC14. If the CPU11 designates deflection width, the DAC14 will send out compensated products to an amplifier 16 and compensates eddy curreny influences without providing a shield between the lens 8 and the deflector 7. High- speed scanning is made possible with practically sufficient accuracy.
